A function too far: Wall-mounted digital scale clock

I'm still not sure exactly how this setup works but it easily qualifies for this year's weirdest mashups short list.

From the website:

Wall-Mounted Digital Scale and Clock

This wall-mounted digital clock has a removable food scale that can be placed on a countertop or table, eliminating the need to provide counter space for both appliances.

The scale is controlled entirely by a touchscreen and it slides over the clock and locks into place.

When removed and used to weigh food or items up to 7 lbs., it uses an infrared signal to transmit its measurements in either metric or imperial readings to the easy-to-read backlit display mounted to the wall.

When not in use as a scale, the display provides time and room temperature.

Includes seven AAA batteries.
